Why would Kate Upton apologize for being sexy?

The smoking hot model picked up the statuette for PEOPLE’s Sexiest Woman at the first-ever PEOPLE Magazine Awards on Thursday night, but she had to acknowledge the awkwardness in store for her younger sibling.

“I’m so, so sorry to my 18-year-old brother,” she joked during her acceptance speech. “Poor David!”

Still, she knows there’s one guy thrilled with her sultry status: boyfriend Justin Verlander, 31, a pitcher for the Detroit Tigers.

“Um, you’re welcome, Justin,” Upton, 22, added with a laugh.

Not that the Sports Illustrated Swimsuit Issue cover girl is always looking hot.

Asked about her latest least sexy moment backstage, she replied, “Oh, this morning.”

“It was ugly. I almost posted an ‘I woke up like this’ [photo] but I didn’t want to be so truthful,” she told PEOPLE. “Who’s pretty at 4 a.m. unless they’ve been out all night?”

Beyoncé may beg to differ, but from the rest of us mere mortals: preach.
